note 93918 added to function.substr

Tested several suggested replacements for substr: $start = 0; $len = 15; $str = "1234567890ô234567890"; echo "substr: [".substr($str,$start,$len)."]"; echo "<br>"; echo "preg_replace: [".preg_replace('#^(?:[\x00-\x7F]|[\xC0-\xFF][\x80-\xBF]+){0,'. $start .'}'.'((?:[\x00-\x7F]|[\xC0-\xFF][\x80-\xBF]+){0,'. $len .'}).*#s','$1', $str)."]"; echo "<br>"; preg_match_all("/./su", $str, $ar); echo "array_slice: [".join("",array_slice($ar[0],$start,$len))."]"; echo "<br>"; echo "mb_substr: [".mb_substr($str,$start,$len)."]"; When the above file has been saved in ANSI: substr: [1234567890ô2345] preg_replace: [1234567890] array_slice: [] mb_substr: [1234567890ô2345] When the above file has been saved in UTF-8: substr: [1234567890ô234] preg_replace: [1234567890ô2345] array_slice: [1234567890ô2345] mb_substr: [1234567890ô234] So be careful which encoding while saving the file. Anyone has a fix that works for ANSI and UTF-8 files? ---- Server IP: 208.69.120.35 Probable Submitter: 80.139.116.52 ---- Manual Page -- http://www.php.net/manual/en/function.substr.php Edit -- https://master.php.net/note/edit/93918 Del: integrated -- https://master.php.net/note/delete/93918/integrated Del: useless -- https://master.php.net/note/delete/93918/useless Del: bad code -- https://master.php.net/note/delete/93918/bad+code Del: spam -- https://master.php.net/note/delete/93918/spam Del: non-english -- https://master.php.net/note/delete/93918/non-english Del: in docs -- https://master.php.net/note/delete/93918/in+docs Del: other reasons-- https://master.php.net/note/delete/93918 Reject -- https://master.php.net/note/reject/93918 Search -- https://master.php.net/manage/user-notes.php
